I noticed a lot of questions here are about connecting more than one internal network to the internet. I dont know the exact answer myself (until now ;-), but how does one combine multiple homenetworks and then connect all to the internet with internet connections sharing in general. So no answer about setting up ICS is wanted (I know that already)..... To illustrate this (general) problem: If one home network is wireless and the other is a cat /utp wired network. The wired network is connected with a router to the internet. How can the wireless network use the router thats connected to the internet too, with minimal additional hardware required? I guess to connect seperate networks in general one needs a (hardware of software) router. How is this done practicaly in the setup described above? How is the wireless homenetwork connected (with a 2nd router?) to the wired one? An even more general question would be: How to connect 3 different homenetworks: A BNC wired, a CAT/UTP wired and a wireless network. Can this be done with minimal hardware; only normal NICS and some (cross)cables?

Do you have a spare port on the router? You should be able simply to connect the wireless hub to the router. I'm presuming that yours has an ethernet port on it. If you are out of ports, drop in a HUB or Switch and that'll give you 4 / 8 /16 /32 or whatever number of access ports you need. All PCs should then see the router and access the internet.

Uhh well the whole idea was: Can this be done without having to buy hardware (wireless) routers, hubs or switches, so: No, I dont have a spare port because I dont have a router and no wireless hub at all! ;-) Here are some other suggestions of mine for solving the problem: - Connecting a network (LAN) to the Internet , which is a network itself (a WAN) must be pretty much the same as connecting local networks to each other. - Normally your LAN is connected to the internet with a router. So if you have more than one LAN you are able to interconnect them with a router! - Hardware routers which can handle both wired and wireless NICs are a solution, but also software routers are possible. - To connect 3 different LANs (A=cat/utp,B=wireless and C=bnc)this is my suggestion for a setup: First think of A,B and C as if they were 3 computers. The hardware needed to connect them is either 3 network interface cards (NICs)and a hub or switch and if only NICs with cat/utp are used 2(n-1)=2(3-1)=4 NICs are needed. If older NICs with BNC connector and coax cable is used the 3 can be connected with only 3 old NICs (of course also 3 T-connectors, 2 coax cables and 2 terminators are needed now). For simplicity (and economic;-) I choose this last option to go from here. These 3 old NICs each are placed in one computer of network A, B and C respectively. So every LAN will have at least one computer with 2 NICs. For example the wireless LAN will have one computer with an old NIC and a wireless NIC. Now the IP adresses of the 3 old NICs can be set to: - 192.168.0.10 for LAN A - 192.168.0.20 for B - 192.168.0.30 for C The NICs in that machine will have respectively: - 192.168.0.11 for A - 192.168.0.21 for B - 192.168.0.31 for C Now the router(internet connection sharing)sofware is installed on these machines and if asked for an NIC that is "physically" connected to the internet the old NICs are choosen (although they are not connected to the internet at all in this stage!). For example: The machine in network B must be setup to share its internet connection by choosing the old NIC (with IP=192.168.0.20)as the NIC thats connected "physically" to the internet and the wireless NIC as the gateway for other computers within the wireless network. These other (wireless) computers will have IP adresses of respectively 192.168.0.22, 192.168.023 etc. For network A and C the same applies. Since network A,B and C are physically connected this newly formed network is your LAN now! This LAN can now be connected to the internet as normal with a router. If this is a software router in another computer which is standalone (not a computer inside network A,B or C) the IP adres of the card that is REALLY physically connected to the internet can be set to 192.168.0.1 and the second card has IP 192.168.0.2. Now configure the old NICs: Their Gateway must be set to 192.168.0.2. The last step if possible: The NICs with IP 192.168.0.1 and 192.168.0.2 are placed inside a computer within network A, B or C that has only 1 NIC until now. This computer now has 3 NICS. For example if the computer with IP=192.168.0.32 is used (the second computer in LAN C)for this it will have Internet connection sharing installed, but if someone is browsing the internet on that computer it will get its data from the internet via this route: (IP adress from Internet Service Provider) > 192.168.0.1 > 192.168.0.2 > 192.168.0.30 > 192.168.0.31 >192.168.0.32 As I said I havent tried myself but hopefully someone will try this (or a variant) and report if it works....... Maybe its even possible use Pfff that was long and boring stuff.....;-)

First we need to know what equipment you have. Wireless - How many wireless NIC's do you have? How many PC's? Do you have a access point or are all PC just using a wireless card? Wired - CAT5 - How many PC? How many NIC's do you have? You stated in your first post that they are connected Via a router to the internet, Then in your second post you say you dont have a router. Which is it? BNC - How many PC? How many BNC NIC's do you have? Without knowing what hardware you curently have no one would be able to tell you how to set it up! This sounds like a Q I would have gotten in networking school... Are we doing your homework for you?

First off all: I havent had any computernetwork education at all in my life ;-) so i am not asking you to do any homework. If you read well, this is a GENERAL problem, which involves combining mixed LANs, without the use of HARDWARE routers, switches,hubs, wifi accespoints, whatever.... I guess I answered this theoretical problem myself. I only have to remark that the last step I proposed ( about using a computer in one of the subnetworks as the sofware router to the internet). I guess its possible in theory, but it makes not much sense. For the router to the internet its better to use a standalone computer which is on top of the pyramide LAN stucture. So, only if the wireless LAN is Bleutooth it can have more than 2 computers. If the situation is this: 2 desktops, 1 laptop, 2 wireless NICs and 3 normal NICs my solution would be: - 2normal NICs in the first desktop that acts as a router to the internet. - desktop 2 connected to desktop 1 with normal NIC acting as a router to the laptop by means of the 2 wireless NICs The backdraw for this solution is that both laptops need to be running to allow the laptop connecting to the internet. By reading this forum I think in this perticular case other solutions are possible too: These solutions have 2 normal NICs and a wireless NIC in desktop 1. Only desktop 1 has to be running to allow browsing on desktop 2 or the laptop. I guess one solution involves "bridging" of (wireless en normal) NICs. Another solution would be if 2 versions of proxy/router software is used in desktop 1....
